Application led December 14, 1927. Serial No. 240,002.

My invention relates to a means for operattrol the throttle.

The general objectl of my invention is to provide a practical and noveldevice for the indicated purpose which will beeiective for its purposeand convenient of operation.. The nature of my invention and its dis--tiguishing features and advantages will clearly appear as thedescription proceeds.

Reference is to be had to the accompanying drawings forming part of thisspecification, it being understood that the drawings are merelyillustrative of examples of the invention.

eratmg an accelerator and embodying my invention;

Figure 2 is alongitudinal vertical section as indicated by the line 2-2of Figure 1;

Figure 3 is a cross section as indicated by the line 3-3 of Figure 2;

Figure 4 is a side elevation illustrating an- .otherform of theinventionadapted for embodiment in an automobile when manu factured instead ofconstituting an attach' ment to an automobile, asin the case of the formshown in'Figures 1 and 2.

In carrying out my invention in the form shown in Figures 1, 2 and 3which is adapted vto be emplaced in an automobile by the owner, thenumeral 10 indicates the basefwhich cured by a pivot bolt 16 t0 saidpedal 14.

A may be of any approved design, and'having means such as screw holes110 to receive fastening screws for securing the device in position onthe floor of an automobile.

T-he Abase 10 is formed with a lug ll in which. isa vertical oblong slot12 through which passes .a' pivot bolt 1 3, which rockably secures apedal 14. Depending from the pedal' 14 at one end is a pressure head 15se- To limit the rocking movement of the pedal v 714 after thedepresslonrthereof I provlde a stop screw 17 adjustable in the base 10to vary Y the movement permitted vthe pedal 14 in rlsing after adepression. Said stop screw 17 is held in adjusted position by aset nut18.'

'The top surfaceof the lu 11 is rounded and the opposed rounded sur ace'of the pedal 14 on the underside has friction material 19, -such asbrake lining material or the hke.

g the accelerator of an automobile to con Figure 1 is a plan view of adevice for opl ignora or down owing to the. slot 12. and Divot bolt 13,so that the friction material l9will bind against the upper surfaces ofthe lug 11 and prevent accidental depression of the pressure head l5until such .depression of said. pressure'head is eiiz'ecteddeliberately.

Inuse foot pressure applied to pedal 14 l can be so distributed. on saidpedal as to cause a depression of the pressure head 15 by rockingmovement of said pedal about theJ axis of the bolt 13. 1

The pressure head 15,- whenthe device is in the form of an attachment toan automobile, bears against the usual accelerator button A to depressthe accelerator for throwing open the throttle valve in the usualmanner.v

To cause the pedal 14 to be restoredto its normal position afterdepression I provide lift spring 25 secured by bolt 26 or the like tothe under .side ofthe pedal 14, the free end of the spring bearingagainst the base 10 in a manner tending to lift the pedal.

The form shown in Figure 4 is adapted to be incorporated in .anautomobile when made at 1 i the factory. In said ligure those parts.corresponding with the first described construction bear the samerefeernce letters as in Figures 1 to 3. The base 210 in Figure 4 Iisadapted tobe made rigid in any suitable man; A

ner with the door of anautomobileyand is formed with sleeve 20 throughwhich accelerator spindle a extends from 'the pivot bolt 16.,v

The said accelerator s'pindle'a has secured boltt22exte'nds any suitableconnection 23 to the throttle valve, not shown. The numeral 24 indicatesset nuts to hold the c levis 21 in l adjusted position.

I'would state furthermore that while the `illustrated examplesconstitute practical em,

bodiments of my inventionI `do not limit 'myself to the exact detailsherein illustrated, since, manifestly, thesame-.can be considerablyvaried without departure from the spirit of the invention asl defined inthe appended Y accelerator,-includinggal base, a .peddl/ e 2 y 1,7oo,e43
